To allwhom it may concern:

Be it known that I, PAUL O. E. FRIEDRICH, a citizen of the UnitedStates, residing in the city and county of Philadelphia, State ofPennsylvania, have invented a new and useful Vacuum N ursing-Bottle, ofwhich the following is a specification.

My invention consists of a novel construction of a vacuum nursingbottle, wherein I employ a vacuum bottle inclosed in a suitable casing,the latter being open at both ends and having its upper end constructedso as to engage between it and the mouth of the vacuum bottle, asuitable nursing nipple which may be of the usual character, provisionbeing made for enabling the bottle to be readily removed from its casingby the withdrawal of a cushion closure from the larger or the bottom endof the casing, said closure being held in position by means of a bayonet'oint or joints of similar character and the ottle being thus cushionedin respect of its casing at its upper and lower portions, the same isnot hable to break in case it is dropped by the infant, nurse orattendant.

Heretofore, one objection to the use of a vacuum bottle as a nursingbottle has arisen from the fact that without a suitable casingsurrounding the same, there is great danger and liability of the bottleto break if dropped by the infant, nurse or attendant, in which case'asis well known, an explosion would take place with the liability of theinfant or attendant being harmed by the flying fragments, whereas in myconstruction no such accident can occur, since the bottle is preventedfrom lbreakage by reason ofthe cushioning devices at its opposite ends`To theabove ends my invention consists broadly of a novel constructionof vacuum bottle having a nursingnipp'le secured to the mouth thereof inconjunction with an open ended metallic or other-casing, the smaller-endof said casing having its walls converged or deflectedA inwardly soas to hold the nurs-` ing nipple tightly in place and the larger orlower end of said casing being provided with a removable closure havinga cushioning device located between said Iclosure and ,the base of thevacuumbottle.

` It further c'onsistsofI othernovel features. of constructionfall aswill. be hereinafter fully set forth.

For the purpose of illustrating my inven tion, I have shown in theaccompanying drawings one form thereof which is at present preferredby'me, since the same has been found in practice to give satisfactoryand reliable results, although it is to be understood that the variousinstrumentalities of which my invention consists can be variouslyarranged and organized and that my invention is not limited to theprecise arrangement and organization of these instrumentalities asherein shown and described.

Figure 1 represents 'a side elevation of a vacu'urnpnursing bottle andits adjuncis, the casing thereof beingfshown in section. Fig. 2represents on an enlarged scale, a side elevation of the-upper portionof the bottle seen in Fig. 1, the nursing nipple and casing being shownin section. Fig. 3 represents a side elevation of the removable. closureof the larger or bottom end of the casing.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings: 1 designates my novel vacuum nursing bottleand its adjuncts, the same comprising the vacuum bottlev '2 which latteris composed of the outer walls 3 and the inner walls 4, the spacing 5therebetween having the air exhausted therefrom by any suitable vacuumproducing means, which may be applied to the teat 6 which latter issealed after the completion of the exhausing operation and the interior7 of the bottle being adapted for the reception of the infants milk orother fluid.

8 designates the mouth of the bottle upon which is supported the nursingnipple 9, the latter having the suction opening 1() therein and the base11 ofthe nipple being drawn downwardly over said mouth 8 so as to beengaged and encircled by the converging open endedwalls 12, of thecasing 13, which may be of metal or other suitable material. Thelower'portion of the casing 13 is provided with the inwardly extendingpins 14 which are adapted to enter the an'- gular slot 15 of theupwardly extending wall lfof the closure 17, the latter being preferablyrovided at its' base with the milledor knur ed portion 18 'which has itscentral portion. 19 slightly elevated, as will be understood from Fig. 1so that the annular chamber 20 is-forrnedfor the reception of the ends'21` of. the resilient cushion or its equivalent 22, `the latter beingpreferably a body of rubber or other resilient material of semisphericalshape and adapted to lightly contact with the base 23 of the vacuumbottle.

The manner of assembling the parts will be readily understood by thoseskilled in the art since it will be ap )arent that the attendant firstremoves t e nipple 9 from the.

vacuum bottle 2 and having filled the same with the milkor other liquidwhich is desired to give to the infant, the nipple 9 is laced inposition. The closure 17 having lieen removed the bottle isinsertednipple end first into the lower portion of the casing 13 untilthe converging walls 12 engage the base portion of the nippleasindicated in Figs. 1 and 2. The closure 17 is then placed in positionand there retained by giving the same a slight turn, whereupon it willbe seen that the mouth and base of the bottle are tightly held andcushioned by the resilient members 11 and 22 so that the bottle can bedropped or rolled around without danger of breakage and the correlationof the converging contracted wall 12 with the base l1 of the nipple atthe mouth S of the bottle will cause said base portion of the nipple tobe tightly compressed so that no leakage can occur from the mouth of thebottle into the space between the bottle and the casing 13.

It will be seen from my invention that the casing 13 by reason of itspeculiar construction and correlation with the base of the nipple andthe mouth of the bottle has a double function, since it not only servesto incase the vacuum bottle and lprevent the same from all liability 'ofbreakage, but it further acts to prevent leakage from the mouth of thebottle into the space between the bottle and casing and furthermore,upon the removal of the closure 17 the bottle can be readily withdrawnfrom the casing and the nipple and the bottle cleansed or sterilizedaccording to requirements.

It will be evident from the foregoing that by the employment ofa vacuumbottle the milk or other liquid nourishment intended for the infant, canbe initially heated to any prescribed degree and after being inserted inthe bottle, it will retain its initial prescribed temperature for a longperiod of time and sol far as I am aware, I am the first in the art tocombine an open ended easing having the contracted converging smallerend correlated-With the mouth of a vacuum bottle and a nursing nipplethereon in themanner described and m claims to these features are to beinterprete withv corresponding scope.

It will, of course, be apparent that slight changes may be made in thecontour ofthe casing, the mouth ofthe bottle and the mannor of formingthe closure of the larger end of the casing, wlthout departuig from thespirit of my invention and I do not, therex fore, desire to be limitedin every instance to the exact construction I have herein shown anddescribed.

Having thus described my invention, What I claim as new and desire tosecure by Letters Patent, is

1. The combination of a vacuum bottle, a resilient nursing nipplesecured to the mouth thereof, an open ended casing inclosing said bottleand the base of said nipple and having its smaller end provided withcontracted conver ing walls extended above the mouth of sai bottle landprojected over and beyond said mouth soas to compress the base of saidnipple against said mouth, and a closure for the larger end of thecasing, said closure being adapted to contact with the base of saidbottle, whereby the latter is held longitudinally immovable in. saidcasing.

2. 'The combination of a vacuum bottle, a nursing nipple' secured tothevmouth thereof, an open ended casing secured-to said bottle andhaving its upper end provided with'converging contracted walls adaptedto compress the base of said nipple against said mouth, a closureremovably connected to the base of said casing, and a cushioning devicecarried by said closure and having its upper'L surface adapted tocontact with the base of said bottle.

3. vThe'combination of a vacuum bottle, a

resilient, nursing nipple secured to the mouththereof, an -open endedcasing inclosing said bottle and having its smaller end provided "withcontracted converging'ends compressing the base of said nipple againstsaid mouth, and the larger or lower end of said casing being providedwithv a closure removably connected thereto, said closure having anannular recess internally located within said closure and a resilientcushioning device carried uponsaid closure and having a ortion thereoflocated in said recess, said cus ioning device contacting with the baseof said bottle.

4. The combination of a vacuum bottle, a nursing nipple secured to themouth thereof, an' open ended casing inclosin said bottle and the baseof said nipple an having the portion engaging said nipple adapted tocompress the latter against said bottle, and means for retaining saidbottle Within said casing. i
